I broke this, I don't know what it is or if I can drive my Integra
 

Hey!

I have a 1994 acura integra and I hit a snow bank yesterday on my ridiculous street but its bloody cold here and now its all turned to ice. I backed up and broke this off the passenger side by my wheel well. Can anyone tell me what this is? My car still runs but there is a ridiculous amount of exhaust under my car.

Thanks
